Fill ids are the ids the fills and reconciliation endpoints return, so you can match them to the trades you already recorded. A voided fill no longer counts toward the account's balance, P&L or rules. After the batch is undone the fills count again and this list is empty (`undone: true`). **Example:** ```bash curl "https://api.hyperprop.com/platform/v1/organization/revert-batches/a1b2c3d4-e5f6-7890-abcd-ef1234567890/accounts/7c9e6679-7425-40de-944b-e07fc1f90ae7/voided-fills?limit=500&offset=500" \ -H "X-API-Key: hp_live_your_key_here" ``` ## OpenAPI ````yaml https://api.hyperprop.com/platform/openapi.json get /v1/organization/revert-batches/{batchId}/accounts/{accountId}/voided-fills openapi: 3.0.0 info: title: Hyperprop Platform API version: 1.0.0 description: >- REST API for the Hyperprop Trading Platform — provision evaluation and funded trading accounts, manage traders and plans, react to account lifecycle events via signed webhooks, and reconcile billing.
